Split the troop into 2 or 4 teams and allocate each a zone. The teams should throw the ball at players in an opposition team, trying to hit them under the knee. When a player is hit he joins the team which threw the ball at him. The team who has the most players (or all the players) at the end wins. We use a hall with badminton court lines marked on it. Each of the 4 teams are allocated a corner each. The area in the middle is a no-mans land. Once only two teams remain we re-allocate the zones so more space is used. ljog0d07]Refinement:ljog0d07]
Use more than 1 ball.
